Available as a two channel or four channel unit the ALXII Workstation is fast becoming the industry workhorse for the international oil and gas pipeline industry. The type of unit has all the facilities of the portable ALXII but x4, allowing one unit to monitor up to four welding heads from a single location. It is supplied with voltage and current measurement on all channels as standard allowing the customisation of the unit by adding whatever combination of options are required to each channel, producing the most versatile and cost effective welding data logging system available.

It is a rugged hard working unit designed to withstand the tough conditions of the working environment but is equally at home monitoring welding procedures, qualifying welders or in a laboratory situation where precision welding of fine components and exotic materials requires the most accurate data logging system.

In a pipeline production situation the ALXII workstation leaves its rivals way behind. The unit is compact, easily moved by one man to allow fast set up and breakdown, thanks to the high quality none intrusive probe connections. Specific pipeline software allows a complete welding procedure from root to cap to be pre-programmed into the system so that a single Workstation can monitor the whole weld or units can be used to monitor preset weld passes in different stations. The units can be networked together so that a single master station can be created where all the welding data can be correlated into a single report.

The ALXII Workstation has the powerful pulse monitoring software option available, which can be fitted to some or all channels in a single unit. Monitoring and reporting of complex STT type welding pulses presents no problems to this model which has the speed and processing capacity to produce instant reports of each weld pass no matter how complex the waveform.

Special software packages are available which enable the full integration of several ALXII Workstations to produce units of 8 channels and above.

The DINSEARCH™ 2-00 is a multiple sensor, magnetic flux leakage system, specially developed for the inspection of carbon steel pipes and tubes 50mm to 100mm diameter.

Using an external probe, DINSEARCH™ 2-00 will detect defects on the inside of pipework or furnace wall tubes in water tube boilers.

Using an internal probe enables the system to be used in large diameter heat exchanger tubes, air pre-heater tubes in boiler installations, tubes in fire tube boilers and some types of finned boiler and economiser tubes.

Inspection is rapid, typically 1 metre per second or faster. Unlike ultrasonic systems, no couplants or water are required, the pipe remains dry.

The following photographs show the various probes that can be used with the DINSEARCH™ 2-00 system.

The smaller sizes of probe can get hot and they require a supply of cooling air. This can be provided by any suitable air line through a filter and pressure controller but it is often more convenient to have an independent source.

Oil and water in site air lines can contaminate probes and effect their workings. This cooling unit provides a steady flow of clean, cool air at the correct pressure.
